ixgbe_poll() is a cleanup routine for Rx/Tx and it makes sense that it will be in the trace, but it doesn't necessarily point to the driver. The ixgbe_poll() is in the trace from a BUG_ON() in mm/slub.c: [409292.391369] kernel BUG at mm/slub.c:3336! If you can reproduce this issue on the current stable kernel you can run it with slub_debug (Documentation/vm/slub.txt))to get a better idea of what is causing the corruption. Also I'd suggest reporting it on the kernel mailing lists. When reporting issues to the community only use the in-kernel drivers, not the one from sourceforge. Also if you can provide details about your setup and the type of traffic you are using we can try to reproduce in house, as we have not seen an issue like this in our testing.
